'Guardians of the Galaxy Vol. 2' has 5 end-credits scenes — here's what they mean for future Marvel movies

If you're as puzzled as Baby Groot after watching the credits, you're in the right place. Marvel

Warning: There are major spoilers ahead if you have not seen "Guardians of the Galaxy Vol. 2."

"Guardians of the Galaxy Vol. 2" is finally in theaters this weekend. If you head out to see the sequel, make sure to stick around after the film.

Marvel loves to add extra scenes as the credits roll and "Guardians" delivers plenty. We're not talking about the usual one or two bonus scenes fans are used to seeing. "Vol. 2" has a walloping five scenes throughout the credits.

Not all of them tease future Marvel movies. Out of the five, three of the scenes are the most important regarding future releases. If you headed out early before catching some or all of the end-credits scenes, we have you covered.

This is your last chance to head back before spoilers!

The first end-credit scene

What happens

Will Kraglin start using the Yaka Arrow now? Marvel

After Peter gave him Yondu's mended Yaka Arrow, we see Kraglin (Sean Gunn) trying master the deadly whistle and arrow combination.

While he struggles to get the arrow to move around at first, Kraglin is then successful in getting the arrow to stab Drax in the neck after his third attempt. As Drax yells out in pain trying to remove it, Kraglin quickly runs off wearing a fin on his head.

What it means

Will Yondu's best bud now one of the Guardians? Disney/Marvel

While it's easy to see this as a quick one-off scene, it looks like Kraglin will be sticking around with the Guardians for awhile. He left his Ravager group to follow Yondu. Now that Yondu's gone, Kraglin could use a place to stay and the Guardians seem pretty welcoming. Peter Quill (Chris Pratt) gave Kraglin Yondu's Yaka Arrow at the end of "Vol. 2" and Kraglin accepted Quill as his Captain.

We're sure we'll see more of Kraglin in "Guardians 3" since Sean Gunn is not only the younger brother of director James Gunn, but Sean also does the motion capture on set for Rocket Raccoon. Maybe he'll be the successor to using the arrow in the next film.

The second end-credit scene

What happens

We see Sylvester Stallone's Ravager character, Stakar, again on a spaceship united with a group of characters ranging from a red, dragon-like creature to a man who looks like he's made out of crystals. Ving Rhames is noticeably there in costume, too.

Stakar tells the group that it's a shame it took Yondu's passing to bring all of them together again. He then suggests they "steal some sh--" together.

Stakar was raised by the Reavers, a group of cyborgs. In "Vol. 2" he appears to be a respected leader of the Ravagers. In the comics, he's also known as Starhawk, a hero who has worked alongside the Fantastic Four and Thor and who has a long lifespan.

Aleta Ogord (Michelle Yeoh)

On the left, you can see Aleta and Stakar joined in "Guardians of the Galaxy Annual #1" from 1991. On the right, is Aleta from the same issue. Yeah, they actually made a "pin-up page" for her character. Marvel

I bet you noticed that Stakar and Aleta share the same last name. Well, that's because Stakar is her adopted brother. But, there's more! The two eventually fell in love with and were married for a time. It gets better. Together, they stumbled upon a statue which merged them together and turned them into the hero Starhawk. Only one of them can ever be present at once. But, yes, there is a male and a female Starhawk.

Charlie-27 (Ving Rhames)

Charlie-27 is space pilot for Jupiter who is the only survivor when his city gets destroyed by a group of aliens. He's teamed up with a lot of different heroes and groups like Thor and Captain America, time-traveling through comics. He also becomes involved in the "Infinity War," which will be the next "Avengers" movie.

Martinex T'Naga (Michael Rosenbaum)

Some more info on Martinex from 1991's annual "Guardians of the Galaxy." Marvel

Martinex is one of the coolest looking characters we've seen so far in the Marvel Cinematic Universe. Since he's from Pluto, his skin is covered in a crystal layer which allows him to withstand the planet's cold temperatures. Like Charlie-27, the alien race, the Badoon, destroyed every other Plutonian while he was away from the planet. In "Guardians of the Galaxy Vol. 2" we see Martinex traveling around with Stakar.

Mainframe (voiced by Miley Cyrus)

There's a reason he looks similar to Iron Man. Marvel

Mainframe is a future iteration of Vision, Tony Stark's AI that became sentient, on an alternate Earth. Stark made an android using Iron Man armor and that became Mainframe. Even if he gets destroyed, a beacon inside of Mainframe will upload his consciousness into a replacement suit back at Stark's location. Pretty handy. What you may not have expected is that Miley Cyrus herself lent her voice to the character.

"I was watching 'The Voice' and I [thought] she's so likable and her voice is awesome, she's got the best voice. And then I asked Kevin, what do you think about casting Miley Cyrus as the voice of Mainframe? He was like well if you think we can get her… and I got her to do it," he said.

Krugarr

Krugarr is a wormlike creature who eventually took over as the Sorcerer Supreme after Doctor Strange. In the end-credits scene we see him using magic similar to Strange.

Yondu (Michael Rooker) was also part of the original Guardians. Stakar's line about Yondu's death bringing them all back together suggests that they were once a rag-tag group just like the one Yondu watched Peter Quill cobble together years later. It's something Marvel head Kevin Feige said as much about at the "Guardians 2" press junket in Los Angeles.

"When James had the idea to do more with the Yondu character — who is also an original Guardian — there was the notion that he had a team once like Peter does now," said Feige, according to CNET. "That'd be fun to see them."

Will we see them again?

Maybe! Director James Gunn has said he definitely has plans for Stallone in future Marvel projects.

"My plan is to see more of him," director James Gunn told the Sun. "I'm not sure about him appearing in Vol. 3, we'll have to see about that, but it's our plan to see more of Stallone. Kevin (Feige) and I are working on what is going to become of the Marvel Cosmic Universe and where it's going to go. We plan to see the rest of them in the future."

In "Vol. 2" it looks like Stakar isn't Starhawk yet, so there's a possibility of seeing the two merged at some point in the future.

The third end-credit scene

What happens

Ayesha's not done with the Guardians yet. Marvel

Ayesha, one of the villains of "Guardians 2," looks disshelved and defeated after losing to the Guardians of the Galaxy not once, but twice. Instead of giving up, she's still seeking revenge on them for stealing some valuable batteries, which power her planet. Imagine having that big of a grudge over some batteries.

One of the Sovereign people comes to Ayesha's side to tell her, "High Priestess, the council is waiting."

"They are perturbed I wasted their resources," Ayesha says in response. She doesn't think that will last long. Ayesha reveals she has been working on something that will fix their problems with the Guardians and shows off a birthing chamber.

"That is the next step in our evolution," she says. "I think I shall call him Adam."

The camera then pans over a giant pod housing some unknown being. If you recall, early in the film, Ayesha tells the Guardians all life on their planet grows in pods, so it's not odd to see her with a large chamber.

Who is Adam?

The introduction of Adam Warlock in the comics. Marvel

Ayesha is referring to Adam Warlock, a character which fans speculated appeared in a scene in the first "Guardians of the Galaxy." For what it's worth, eagle-eyed viewers will note the cocoon Adam is inside in the "Guardians 2" end-credit scene looks somewhat similar to the one we saw in the 2014 film. (Maybe Ayesha even got it from the Collector's destroyed vault.)

Here's the mysterious pod that was in the Collector's room in the first "Guardians."Marvel

In the comics, Warlock was also an artificial human created by scientists called the Beehive in the hopes to create the perfect human specimen. Unfortunately, that's not what Adam ended up being. At this point, Adam didn't even have a name. He was only known as "Him." When he learned his creators wanted to use him for evil, he fled. A later run-in with Thor (it was messy) left him at death's door before he was reborn and named Adam Warlock by another former scientist.

The reason Warlock is so important is because he's the key to the final Infinity gem stone, the six powerful relics which have been slowly teased throughout the Marvel Cinematic Universe. In the comics, he's in control of the soul stone — the one we haven't seen on screen yet — which allows the owner to steal other souls.

That sounds bad

Yeah. It's a bit worse when you know the gem kind of has a mind of its own and has an unquenching thirst for souls. Things start getting really crazy when you know the gem contains an entire separate universe that holds all of the souls it has captured.

If Ayesha and her people want to use him for their own vendetta against the Guardians, they may have another thing coming. Of course, the Marvel films may want to depict him as a straight up villain or anti-hero and there is another version of the character, called the Magus, which is evil.

It looks like the days of Baby Groot are over, for now. Get ready to see a full-fledged Groot the next time we see the character on the big screen. The Guardians will have a role to play in the next "Avengers" movie, "Infinity War." That's not a surprise when you know Gamora and Nebula are the daughters of Thanos, the expected villain of "Infinity War."

Marvel Studios head Kevin Feige told CinemaBlend "Infinity War," will take place four years after "Guardians of the Galaxy Vol. 2," giving Groot plenty of time to grow. After seeing "Vol. 2" you know it also takes place shortly after the events of the end of the first film from 2014.

The fifth end-credit scene

What happens

Stan Lee is in about every Marvel movie. Jason Merritt/Getty

We see Stan Lee in a spacesuit with three alien figures who are walking away from him, appearing bored by his stories. He asks them where they're going, saying, "You were supposed to be my lift home. I have so many stories to tell."

What it may mean

This is an extension of an earlier scene in the film where we briefly see Lee in space with the same figures. Most will probably laugh off this tiny scene, but if you pay attention to the dialogue here along with the line Lee delivers earlier in the film, the scene takes on a completely different meaning.

Earlier in the film, Lee's character starts to tell the figures about the time he was a delivery postman. Sound familiar?

If you pay attention to the Marvel movies and television shows, you'll know Lee pops up in small cameos throughout the Marvel Cinematic Universe (MCU). He's had over 30 cameos across television shows and Marvel movies to date. Over the years, he unsuccessfully tried to drag Thor's hammer with his pickup truck and he appeared as a Fed-Ex delivery man at the end of 2016's "Captain America: Civil War."

The scene suggests that Lee's character across the MCU is one and the same and that his character has been going on adventures keeping tabs on various characters in the Marvel Universe. Here, it looks like he's reporting in to figures known as the Watchers. It appears Lee is an informant to the Watchers or a Watcher himself, something fans have previously had theories about. According to IMDB, Lee's credit in the film reads "Uatu the Watcher."

Who are the Watchers?

The Watchers are one of the oldest living species in the Marvel Universe created by none other than Stan Lee himself and Jack Kirby.

According to Marvel, Watchers choose different areas of the universe to passively observe what's going on in the far reaches of the galaxies. Uatu watched over Earth and its star system, which would be a perfect explanation for what Lee's character has been doing in his multiple Marvel cameos. In the "Guardians" post-credit scene, it looks like Lee is divulging his many observations to other Watchers.

Since the Watchers are absently seen walking away from Lee, are they not interested in what he has seen? It will be interesting to see Lee's next cameo in the MCU when "Thor: Ragnarok" hits theaters in November. We'll have to wait and see if all of Stan Lee's cameos really are connected or whether or not this was just a clever wink and extra Easter egg for comic fans.
